I think this might be caused by an incorrect remapping of the BMA423 axes.
This is currently set up here: https://github.com/sqfmi/Watchy/blob/b3e11b76ebdcc523f0b63b6ef8d02ffbaa23447f/src/Watchy.cpp#L584
struct bma423_axes_remap remap_data;
remap_data.x_axis = 1;
remap_data.x_axis_sign = 0;
remap_data.y_axis = 0;
remap_data.y_axis_sign = 0;
remap_data.z_axis = 2;
remap_data.z_axis_sign = 0;
But after checking with the datasheet of the BMA423. I think it must be this:
struct bma423_axes_remap remap_data;
remap_data.x_axis = 1;
remap_data.x_axis_sign = 0xFF;
remap_data.y_axis = 0;
remap_data.y_axis_sign = 0xFF;
remap_data.z_axis = 2;
remap_data.z_axis_sign = 0xFF;
After changing the remapping, even Wrist Wear detection works excellent (I'm using the newest BMA423 library on the ESP-IDF, not the Watchy library).
I've added a PR for this change in #26
Thanks @LeonMatthes! Merged . We're working on updating our library to use the latest: https://github.com/BoschSensortec/BMA423-Sensor-API
The step count from the BMA423 is inaccurate. Just shaking my arm around increases the step count by a few 100s. I removed the step count function altogether from the 7-seg watchface example.
